In the original project, I used sin and cos to make the tube twist and turn. Then I realized you can achieve the same (*) effect WITHOUT trigonometry, while making this animation: https://scratch.mit.edu/projects/424934198/ (*) Almost the same; with turbo it's entirely different from the original. Use at your own peril.
